February 25, 2005
WSU’s Center for Sustaining Agriculture & Natural Resources, in partnership with the Yakima Valley Dairy Federation and Washington State Dairy Federation, hosted a one-day workshop on anaerobic digestion of dairy manure in Sunnyside, Washington. The workshop provided an opportunity for dairy producers and others to learn more about the technical and economic performance of commercially available anaerobic digestion systems, financial assistance and regulatory concerns, and project development and management issues. Three nationally known technology experts presented on their approaches to anaerobic digestion. They are Phil Lusk of Resource Development Associates, Mark Moser of RCM Digesters, and Steve Dvorak of GHD Inc. These experts have more than 50 years experience and nearly 60 operating commercial digester projects around the world. More than 10 stakeholder groups came together to sponsor and plan the workshop. As a result of the workshop, Yakima area dairy producers gained a better understanding of existing anaerobic digestion technology, initiated a feasibility study for an anaerobic digester to liquid natural gas project, and identified key issues they are concerned with as they consider the adoption of an anaerobic digester for their farms.

Anaerobic Digestion 101 — Mark Moser, RCM Digesters (Biothane)
Mark is one of the founders and President of RCM Digesters. He was trained as an agricultural engineer with special emphasis on livestock manure management. Over the past 21 years Mark has focused on methane production and recovery and nutrient management. He is responsible for development, design and completion of projects including: 30 anaerobic digesters for methane and on-farm electricity and heat production; 30+ farm waste storage and nutrient management plans; consulting services to public and private clients for waste management and/or methane digesters in Armenia, Belize, Chile, Colombia, Costa Rica, Ireland, Japan, Korea, Mexico, the Philippines, the United States and Taiwan. He has performed consulting tasks for the USEPA, the AgSTAR program, and USDOE on pollution potential from farm waste, farm waste management and potential recovery of energy and fertilizer from farm waste. He has designed portions of several farms including a 500 cow dairy and a 36,000 head swine facility. Other work has included environmental regulatory compliance consulting for farms and industries and expert witness services.
Anaerobic Digestion 101 — Steve Dvorak, GHD Inc.
Steve Dvorak, owner of GHD, Inc., is a UW-Madison engineering graduate and a registered professional engineer in the State of Wisconsin. Steve’s experience in anaerobic digesters began almost 20 years ago with the installation of an anaerobic digester at a food processing company in Green Bay – one of the first ag-related digesters in the state and one that is still currently operating.
GHD, Inc., has been a leader in the environmental industry for the past 14 years, specializing in petroleum and farm related environmental engineering. GHD, located in Chilton, Wisconsin, has successfully designed and installed their patented two-stage mixed plug-flow digester system across the nation. Their anaerobic digesters are cost-effective and require low maintenance. By-products from the digester system include electricity, bedding, heat and liquid fertilizer.
11:15 Technology Panel (open forum Q & A with all morning presenters)
Lusk, Moser, and Dvorak responded to general technology questions from the audience.
